How much will JPS save based on ESET Energy Path

Without boring you with details here is the summary of my calculations on what savings I believe JPS is likely to see once the plants mentioned in the previous post are up and running. Figures below are in US$
Annual savings (ADO – LNG Bogue 120 mW) $           134,537,321
Annual fuel savings (HFO- LNG-190 mW) $        89,918,562.57
Saving per annum replacing 85mW HFO with Coal ( Jamalco) $        65,208,920.64
Total fuel savings- fuel switching $           301,194,797
Working out how much the end user will see ie me and you is a lot more tricky and will require a lot more work than I was able to do just now.  I will however by working on something and should have a rough estimate once I have more information in the coming weeks.

Energy Path Set – ESET . A brief analysis of what has been presented.


I will attempt to provide readers with a brief analysis of what was presented at the first ESET press conference yesterday.
The Gleaner today reported that  ESET has decided to replace the 381 mW project with a set of other power generation initiatives that would cut energy cost by 30%. Now I was not at the press briefing, but I have seen nothing so far in what was presented in the papers to show that this pronouncement is even realistic.
Key points that have been noted via the Gleaner
  1. JPS is to convert its Bogue Plant plant to burn gas ( I will come to this in a second)
  2. JPS is to replace 292 MW of oil fired plant with a 190 mW Gas turbine burning LNG.
  3. Jamalco is to operate a Co-Generation coal fired facility
  4. US Rusal which operates Alpart is to build a Ethane fired power plant .
  5. ESET is to  conduct further due diligence on the various proposals and analysis on fuel supply financing etc.
Point 1.
As far I  know this facility is a dual fuel plant (flexi fuel), which is capable of burning both HFO and LNG and all is required is a source of fuel ie LNG. Savings here but no increase in base load capacity on this 120 mW Power plant. JPS has been in talks for sometime now to get a stable and cost effective supply of LNG for this facility and actually signed an agreement with Canadian firm Fueling Tech Incorporated (FTI) International , which was leading a consortium to assist JPS in this regard.
Point 2
JPS is to replace 292 mW of generation with 190 mW, which leaves a shortfall of 102 mW and has to be replaced somehow . I read nothing so far to suggest how this shortfall will be replaced. It early days yet, so I do expect to hear more  from ESET on this one.
Point 3
Jamalco had a proposal on table to build a 140 mW Cogeneration , to provide its thermal requirements and would off load 85 mW of power in the JPS grid. I am not sure if this is the proposal that is being rehashed almost 8 years later, so I will await further word from ESET on this particular matter.This plant would have been a coal fired plant and as ESET have said the coal would come from Columbia, which was the worlds 4th largest suppler of coal in 2012. The good thing about the coal from Columbia is its low sulphur content, which means lower SOx emissions. I am going to assume this 85 mWto be sold into the grid would help reduce the 102 mW deficit mentioned above.
Typically Co-generation facilities are not used to provide base power given the fact that the facility in question would use what it needs and feeds the remainder into the grid, which makes this more of a Distributed Generation Facility of DG and therefore would  provide a variable supply.
Now a coal fired plant takes approximately 4 yrs to build, so if construction begins late next year, the plant would not come online until  late 2019 !
I will support a coal fired plant, but I would have preferred if JPS was the one developing this facility for true base load requirement.
Point 4
US Rusal Ethane fired power plant. I think this is a none starter for two main reasons
  1. US Rusal is not going to be making any further investments in Jamaica.
  2. Ethene as a source of fuel for a power plant is a major challenge, as the process to transport from where its manufactured to point of use is not mature process given the extreme conditions that it requires. It is typically used where its processed and frankly  I do not see UC Rusal being involved in this process at all, so I would say this particular proposal is akin to flying a kite.
So where does this leave us.
I said the information presented by ESET has offered absolutely nothing new at this stage given what I have mentioned above. JPS lost the chance to replace its aging generators under the original 400 MW project because it was unable to source the LNG require to run its facility.
By splitting up the project into little bits and pieces therefore reduces our bargaining capabilities for cheaper LNG. if each entity is required to find, negotiate and sources it own fuel, which reduces the possibility of that magical 30% we are looking for.
The only way this would therefore work is if one entity ( eg the GOJ) negotiates and sources the fuel, which it in turns sells to the power producers. Recall we attempted this before with Exmar and we all recall how that ended up.
I will not cold pour water yet on the ESET preliminary report and will await further information, but from what has been reported thus far, it fails to inspire any confidence that we can have cheaper sources of electricity and 30% reduction by 2019 !
That folks is my quick analysis of the ESET first report.

ESET- The new energy path, further review.


I got more information last evening in relation to the new course that ESET plans to chart as it relates to the new policy direction for additional/replacement generation on the grid.  The mix is now as follows.
  1. JPS replaces  292 mW HFO plants, with 190mW of LNG fired power plant ( Balance – 102 mW)
  2. Jamalco will build a 140 mW plant of which 85mW will be sold to the grid  ( Bal now 17 mW)
  3. Alpart to build a 50mW Cogeneration plant. ( Now sure how much will be sold to the grid)
  4. 120 MW Bogue to be converted to run LNG ( No increase in generation capacity).
Total new generating capacity  to be deployed  is 380 mW.
Total Installed generating capacity to be available to the grid would be around  290 – 300 mW.
Now let’s explore the various cost involved in getting these plants up and running and what cost would they be able to generate and sell power back into the grid.
I will then give an estimate in terms of the possible reduction in overall cost to the customer when all this is completed and operational.

As one can see this is above the bench mark of US$0.1288 that was set by the Energy Minister earlier this year.
Now how much does JPS save by shuttering its old Gas Fired Plant. Lets explore the HFO fired plant to see what kind of a cost we believe JPS would have been generating at.

Total Generation Cost to meet ROI $      367,983,030.98
Price to the grid $                       0.1881
This is approx 19% reduction in price to the grid. Note this is NOT necessarily the price reduction the customers will see given, the T&D losses, Theft losses etc.
So by JPS would from the above save approximately US$184.66M in fuel cost alone by shutting down its 292 HFO fired plants and build and operate a 190 mw LNG fired plant. There is more savings to come, when we look at the cost now operate the Bogue 120 MW plant .
I will present those numbers later in the week.
Its a lot to digest for now.
